Good Points
Good customer support. They take care of what website you add on their network.

Bad Points
Terrible design of the payment page. All major players update their payment page but not 2CO.
They charge you the setup fee: signup for free and insert the credit card... after they say: Your credit card was charged by this amount....this is not fair! You have to say: "We have this setup fee" from the beginning.

General CommentsStill I will recommend 2checkout payment processor because is reliable and affordable.
